Forwarded from CLIMLIST... Postdoc position to model the spread of radionuclides from fires in areas affected by Chernobyl and the consequences for human health, ecology and biodiversity Description: We seek applications for a Postdoctoral Fellow position to model radionuclide redistribution as a consequence of fires that occur in the vicinity of Chernobyl. The disaster at the Chernobyl power plant in 1986 released more than 130 PBq of radioactivity, with most deposited in nearby areas of Ukraine, Belarus and Russia. Approximately half of this material still remains after natural decay of radionuclides. More than 10,000 km2 were heavily contaminated, and most human activity including forestry ceased in these areas, causing accumulation of firewood for the last 25 years. Because climate change has in addition caused an increase in temperatures and a decrease in precipitation, there is an increased risk of forest fires. Such fires are disproportionately located in contaminated areas as revealed by satellite images. Forest fires produce radioactive smoke that can be transported and subsequently deposited in densely populated areas such as Kiev and Moscow, depending on wind direction and patterns of rainfall. Such redistribution of radioactivity could have dramatic consequences for public health, but also animals and plants, and for the possibility to grow crops and practice farming in large areas that are not contaminated today. The objective of this Postdoctoral Fellowship is to assess the consequences of different kinds of forest fire (minor fires, intermediate fires that affect 30% of the area, worst case scenario of the entire area being affected by fire) on re--distribution of radioactive material. The project will use a state of the art earth system model in which a fire model, SPITFIRE, has been embedded. We will model climate change, risk and distribution of forest fires and determine risk of deposition of radioactive material transported by smoke. We will calculate radioisotopes concentration and deposition fields from which exposure doses can be derived. This will allow health experts to quantify public health and biological consequences of such re--distribution of radioactive material. At an early stage in this work a workshop will bring together fire experts, health experts and ecologists to assess the current state of understanding and the uncertainties associated with modeling fires and radionuclides. The position is for 24 months, and we would like the candidate to start at or close to October 15th 2011. Candidate background: We seek candidates that have a thesis, a superior ability to write papers, and familiarity with numerical modeling. The applications should include a resume, a statement of research interests and the names of at least two references including e--mail addresses and telephone numbers.
